The form and chara ter of the fastening inserting mechanism may vary according to the kind of fastening to be inserted into the shoe by it, and in the present instance it comprises a movable head 3 in which is mounted a driver bar 4. carrying a driver 5, and an owl bar 6 carrying an awl 7. A disk 3% actuated from the main driving shaft E) is provided with a lug 1.0 for lifting the driver bar and driver. the fastening inserting strolie of which made by an arm 11 i'nounted in the bracket 12 and normally under the influence of a strong spring 155. The actuating force of the spring is delivered to the driver bar through the link 14, the ccnstruction being such that the driver bar will be raised by the lug 11) on the disk 8 and then freed to the action of the spring 13. sub tantially 18 in the patent mentioned for driving the fastening into the work supported upon the work supporting born 15.

In the illustrative machine an opening is formed in the work for the reception of av fastening by means of the awl 7 which pass through the throat block 16 and is actuated to form such opening by a toothed segment 17 carried by an arm 18 secured to a, Ifltl shaft 19 actuated by suitable cam means on the main driving shaft as in the said patent. Wl'ien the awl is in the work it is moved tofeed the work over the horn for the ii'isertion of the next fastening by rocking movement of the head 3, which. as des ribed in said patent, may be secured by an ope ing or feed arm 20 carried by a rock shaft mounted in the head frame 2 and suitably actuated from the main driving shaft. The rocking head 3 is operatively connected to the arm :20 by a pin 21 and block 22, the constru tion being such. as more fully disclosed in said patent. that upon rocking movement of the feed arm 20. the aWl will effect feed movement of the work over the horn forthe insertion of the next fastening.

The fastenings may be supplied to the inserting mechanism by means of a raceway 23, and in order to deliver the fastening singly to the inserting mechanism a separator is carried by an arm 24 pivotally mounted at m and actuated by a suitable cam and spring as in the Goddu patent imntioned.

Second to the head frame 2 is the stationary guiding means for separately directing the welt and the welt reinforcing material or strip to the fastening inserting position.

In the present instance the guiding means comprises an arm 21; provided with eloir gated slots 27 through which pass the bolts 28 for adjustably securing thc guiding means to the hcad frame 2. as indicated in Figs. 2 and 3. The arm 21') is provided with a head portion 29 provided with a passage y 30 for the welt 51. the constru tion being such that the welt may be directed through the passageway to the fastening inserting position above the insole and over lying edge of the upper of the lasted shoe sustained upon the work suppm'ting born 15, as indicated in Figs. 5 and (i. llv adjustment of the arm 24' on the head frame the well; may be directed to the fastening inserting position in desired relation with the edge of the insole to secure insertion of fastenings into the welt, upper and insole to properly unite the parts. and provide a pro jecting outer edge portion of the welt for securing the outsole thereto.

The action of the fastening inserting mechanismin driving metallic fastenings to unite the welt, upperrand insole is liable to cause the heads of the fastenings to penetrate the Welt, or pass so far below its surface that the welt may not be properly united to the other shoe parts. This is particularly liable to occur when a welt of soft. thin leather is used and the welt has been put in temper. The present invention overcomes this objectionable condition b v separately directing along with the welt a welt reinforcing strip, which overlies the fastening receiving portion of the welt and supports the head of the fastenings under the blows of the fastening inserting mechanism. and prevents the heads of the. fastenings from penetrating the welt itself. The rein forcing strip is preferably formed of muterial through which the heads of the fastening will not readily pass as they are driven. such as canvas. tape, or the like.

In the present instance. the welt reinforcing strip is carried upon a reel or spool 2-32 rotatably mounted upon a bracket 33 projecting from the head frame of the machine from which it is drawn by the feed of the work. Above and separate from the passageway for the welt in the guiding means. is another passageway for the welt reinforcing strip. These separate passageways or guides for the welt and reinforcing strip may he variously formed. In the illustrated instance of the invention the head 29 has adjustably secured thereto an arm 34 having a head 35 provided with a recess or passageway 36 formed in one surface thereof and overlying the top wallv37 of the guide or passageway 30, the construction being such that the welt 31 and reinforcing strip 38 use to be made sutliciently wide to afford a good :support for the heads of the fasteningswithout the other edge of the strip appear ng at I the outer edge of the welt in the. finished 2 shoe, The welt and reinforcing guides or i5' passageways are therefore so related that the inner guiding edges 39 and 4:0"thereof shall be in substantially the same vertical plane. The arm 34 is adjustably connected to the head 29- the bolt 41 which passes through an elongated slot 42 in the arm and engages the. head 29 which permits-relative movementof the guides or passageways to bring them into the desired'relatiom In some cases it maybe expedient to direct the welt reinforcing strip in its passage from the supply orreel 32 to its guide, and in such cases an arm 43 having a strip enga ing and I directing end 44 may be supporte by: the

shoe, the welt has a tendency to curl over or bend either upwardly or downwariflly, at its projecting outer edge portionas iii is being secured to the upper and insole, and the lo- 5 catienrof the welt with relation to the upper andinsole is liable to vary. Accordingly the invention comprises a'support for the projecting edge of the welt opposite the fastening inserting position and a rest against which the upper of the shoe may bear. This rest is preferably formed as a roller upon the top portion of which the projecting outer edge of the welt' may be sustained and against the side of which the upper of the 4.5 shoe opposite the sole edge may bear. As

illustrated by Fig. 5, the roller is mounted upon a stud 46 carried by a slide 47, which may be secured in adjusted position by a'set screw -18 passing through the slot 49 in the 0 slide and engaging a support connected to the ;head frame or other sustaining means The" roller in the present instance, is frusto-conica-l in peripheral outline as indi catedin Fig. 5, and is received in a seat 51 56 formed in the support 50, the construction being such. that the edge portion of the roller may. project beneath the outer edge portion iofflthe welt and support it, while the face "of the roller bears against the shoe at upper oppositethe edge of the insole.

As the welt and reinforcing strip are separately guidedto the fastening inserting mechanism theirflateral position relative to thempperfgnd edge of the insole is detereach side of the fastening inserting position.

About the toe and in the shank of themined by the two guides or passageways 30 and 36 respectively, and as the shoe is fed by the and fresh supplies of welt and reinforcing strips are drawn therethrough. There is necessarily a short distance between the delivery portions of the guides or passage way and the fastening inserting position due to the throat 16, against the lower surface of which'the'work is clamped by the horn during the fastening inserting o eration, and as the work is fed by the awl t e horn drops slightly as usual to permit the work to be fed. At this time the welt and reinforcing .strip are free between their respective guides and the a-wl which is then in the work and the lateral position of the welt andreinforcing strip is apt to vary with relation to the inserting mechanism. To prevent this an edge gage is provided, preferably one at-each edge of the welt,opposite or at These gages for insuring the lateral position of the welt and consequently that of the reinforcing strip, at the fastening inserting position may be variously formed, and in the present instance of the invention the gage for the outer or projecting edge of the welt is afforded by the end 52 of the support 50 above the top of the roller 45, substantially as illustrated by Fig. 5. The gage for the inner edge of the Welt where it overlies the ilpper 54 and insole 55 comprises an arm 53 adjustably secured to the head frame 2 by suitable means, such as the bolts 56, Fig. 1, the edge portion of said gage being positioned relative to the opposite edge gage 52 to cause the welt to be retained between the in proper lateral relation to the upper'and insole at each side of the fastening inserting position, Fig. 5.

The operation of securing the reinforcing strip, the welt, upper and insole together bv metallic fastenings passing therethrough and the action of the guiding means for directing the welt and reinforcing strip to the fastening inserting position, will be sufficientlv clear from the description of the machine and its operation hereinbefore given. but briefly, it may be outlined as follows: The welt and welt reinforcing strip are separately passed through their respective guides or passageways and the end of the welt'is placed upon the upper and insole of the lasted shoe sustained upon the Work supporting horn with the overlying welt reinforcing strip below the fastening 1 inserting mechanism and throat block. The

horn is then raised to position the work op eratively with relation to the inserting mechanism and the machine is started. The

awl descends and pierces the reinforcing 12b strip, the welt, upper and insole, and then the horn drops slightly to permit the work to be fed by the a d. hi while still in the work moves in the line of feed, thus moving the shoe over the work support and drawing a fresh supply of welt and reinforcing strip from their respective sources ing'mechanism insured during the feed and while the fastenings are being inserted. The fastenings are preferably driven through the work and the penetrating ends thereof are clenched or turned upward into the insole below the reinforcing strip by the horn.
